ramuli, difpofed in a fubverticillate manner, irregularly branched, and very 

 vifibly jointed, with cylindrical joints, of which the length is about equal to the 

 diameter. The colour of this fpecies when frefh appears to be a beautifully 

 deep-red brown; when dry it turns to a very dull brown, tinged with green, 

 wholly devoid of glofs; and the plant at firft fight more refembles a battered 

 fpecimen of C. fpongiofa infefted with fome minute parafite than any other 

 Conferva. It adheres either to paper or glafs. 



The fpecific name of this plant was given by Mr. Brown, and is excellently 

 defcriptive of its mode of growth* and general habit, which are not unlike that 

 of many fpecimens of Hypnum alopecurum. T. 



A. Conferva arbufcula, natural fize. 



B. Summit of a branch, magnified 5. 



C. Portion of ditto 4.
